What string of chess notation is the longest?


In my version, we take some liberties.
1. Assume it is move 7776 and it is black to move. This is still possible in the rules of chess.
2. Assume En Passant is notated (in this case with e.p.)
3. Allow Commentary (in this case !!)
4. Draw offers are notated with (=)
